Observe the figure and answer the questions.
Sachin and Sameer started on a motorbike from place A, took the turn at B, did a task at C, travelled by the route CD to D and then went on to E. Altogether, they took one hour for this journey.
Find out the actual distance traversed by them and the displacement from A to E. From this, deduce their speed.
What was their velocity from A to E in the direction AE?
Can this velocity be called average velocity?
A circular cycle track has a circumstance of 314 m with AB as one of its diameter. A cyclist travels from A to B along the circular path with a velocity of constant magnitude 15. 7 m/ s. Find :
(a) The distance moved by the cyclist.
(b) The displacement of the cyclist if AB represents north-south direction .
(c) The average velocity of the cyclist.
At the highest point, when a body is thrown vertically upwards, the velocity is ______.
A body moves in a circular pattern the ______ of velocity does not change but changes.
If the velocity of the body decreases with time the acceleration is negative and the motion is called decelerated motion.
Assertion: A body can have acceleration even if its velocity is zero at a given instant of time.
Reason: A body is momentarily at rest when it reverses its direction of motion.
Distinguish between speed and velocity.
